Answer:
4.2 mL
Explanation:
- CuO(s) + H₂SO₄(aq) --> CuSO₄(aq) + H₂O(l)
We require 0.025 mol CuSO₄ and the ratio is 1:1, thus<em> we need 0.025 mol H₂SO₄.</em>
We know that the concentration of H₂SO₄ is 6.0 M, so we use the formula
- Concentration = moles / Volume
And <u>solve for volume</u>:
- Volume = moles / Concentration
- Volume = 0.025 mol / 6.0 M
- Volume = 4.2 x10⁻³ L = 4.2 mL
the one that contains molecule's is the tope one
Really hope this helped :)
Answer:
C
Explanation:
Because molecules of solids don't move
while molecules of liquids and gases move.
